Tranny Temps

FrignDope · 08-07-2007, 08:23 PM

Hey all,

I just got a aftermarket guage (autometer) installed to watch temps on my 2007 XE Titan CC (7500 miles) while towing. It was installed the same way as the thread in this forum, through the test plug and I am pegging out the 250 max on the guage. The autometer rep told me that the new titan trannys run hot and is sending me a new guage with a 350 max with a new connector that is metric, but I have seen several members mention the 160-180 range as their normals on older models. So I guess the question is...What is the normally range for temps on these trucks?

Could it possibly be a ground issue or maybe exposed wire hitting somewhere else? Maybe the connector with fix it when changed out? Or do these really run in that range? Anyone have any ideas?

Thanks!

My tranny gauge doesn't move much, but I only tow about 3 to 4000 pounds.

176F is what Nissan calls normal on 2004-2007. 250F pegged is really high and I'd try placing a inline temp sensor instead.

Thanks! I will give the new sensor connection a shot and if that fails then will try the inline.

My tranny never gets hotter than 190 and thats with a good load on it. It usually runs around 175 to 180.

If it was really 250 deg. you would smell the trans fliud cooking the trans to death.

My tranny runs at 140 degrees. I had problems with high temp readings too. For solution, read my thread:

Installed Diff. temp gauge

Are you sure that is the right thread? All i read was about a DIFF gauge install not a tranny gauge.

The point being made, was to use a 12 Volt regulator (typically called a 7812, which has a TO-220 Style Case as was described) to ensure consistant and reliable readings. Post #36 made referance to both gauges being used. Excellent info, surprising it is needed for a gage. I'd assume it to be built in.
